Minneapolis Specialty Gas Equipment Spotlight: Gas Purifiers


It’s surely no secret that our main concern at Toll Company is supplying specialty gases for commercial, industrial, medical, scientific, and agricultural use. But customers recognize they also can count on us for the gear required to transport, stock, check on, and employ those gases safely. One such type of equipment they appreciate is our line of gas purifiers.

The Minneapolis semiconductor industry especially looks to us for point-of-use gas purifiers that remove impurities down to part-per-trillion (pptV) levels. This degree of purity is necessary for fabricating not only semiconductors but also [[various display, LED, and solar products.

In particular, we provide …

  • high-pressure gas purifiers, these versions made for use in all types of laboratory and industrial projects where oil or water have to be kept out of a gas so as to improve its efficacy and prevent equipment shutdown.
  • gas purifiers that, while much like our high-pressure models, are made to take care of higher capacities at a lower working pressure.
Note that these two types of purifiers must used with specially engineered replaceable cartridges containing one of a host of different adsorbents. Relevant to the cartridge/adsorbent needed, these purifiers can eliminate more than oil and water from industrial process gases; they can also eliminate water from inert gases and saturated hydrocarbons, eliminate a variety of particulates, and eliminate water from unsaturated hydrocarbons – acetylene, for example.
  • a series of gas purifiers specifically designed to exclude up to 1% of oxygen from a hydrogen stream down to a level under 1 ppm. They do this by catalytic action. Provided the catalytic materials aren’t fouled (particularly by sulfur and halogens), they’ll work pretty much forever and not need regeneration.
